Answer:
y
Step-by-step explanation:
The expression
y = f(x)

Answer:
B.
Step-by-step explanation: Because when you count them down to 3/5 It's more in the negative.
It equals to 4 + 19x , it’s not that hard
Answer:
scientific notation, the number to the left of the x must be between 1 and 10, so you have to move the decimal place until that happens - which in this case means moving it 2 digits to the right.
the x 10^ is standard, the only thing you need to change is the exponent. a negative exponent means you move the decimal to the left, and a positive exponent means to the right. you just count how many decimal places you have to move to get from 1.23 to .0123, and in which direction. here, you have to move it 2 places to the left, so you end up with 1.23 x 10^-2
